Well it was worth a shot but it was still a lot to hope for. It's not necessary to remake the patch from scratch only to find where the functions the patch is referencing were moved and changing the ".org"s and "bls" etc in the sourcecode. Even for US to EU everything only shifted around about...
I obviously don't have your version of the rom so I'm obviously not 100% sure this works but you could always try building the patch from source using your rom as input and hope none of the important stuff being referenced by the patch are moved around...
Finally got around to restoring the source code after accidentally losing a lot of it. Releasing it so I don't have to worry about it again.

Also download link in the first post was updated to include patch for EU support.
At the moment it has all the features and stuff that I planned for it to have at the start so I don't think there's anything really left to update about it.
Releasing the source code for this for whoever's interested. Don't want to accidentally lose it and have it go to waste.
